Engine oil
Engine oil specifications
The grade of engine oil should be selected in accordance with
precise specifications.
The engine of your vehicle has been factor y-filled with a high-grade oil which you
can use throughout the year - except in extreme climatic regions.
You can mix various oils together with each other when refilling with oil. This does
not, however, apply for models with flexible service intervals (QG1).
Engine oils are, of course, undergoing co ntinuous further development. Thus the
information stated in this Owner's Manual is only correct at the time of publication.
Škoda Service Partners are informed by Škoda Auto a.s. about current changes. This
why you should always have engine oil changed by your Škoda Service Partner.
The specifications (VW standards) stated in the following must be indicated sepa-
rately or together with other specifications on the bottle.

Caution
Only the above-mentioned oils
may be used on vehicles with flexible service inter-
vals (QG1). We recommend always refilling with oil of the same specification since
this will maintain the properties of the oil. In exceptional cases, you must top up
only once engine oil complying with Sp ecification VW 502 00 (only for petrol
engines) or Specification VW 505 01 (only for diesel engines) to maximum 0.5 litres.
You must not use other engine oi ls - risk of engine damage!
Note
•Before a long drive we recommend th at you purchase and carry with you
engine oil which complies with the specif ication for your vehicle. Consequently,
you will always have the correct engine oil for refilling.
•We recommend using a preservative from the Škoda original accessories
offered by your Škoda dealer.
•For further information - see Service shedule.

Oil level within range
–You must not top up the oil.
Oil level within range
–You may top up the oil. It is possible that the oil level may then be
within range after doing this.
Oil level within range
–You must top up the oil ⇒page 212. It is sufficient, once this is done,
to keep the oil level is within range .
It is normal for the engine to consume oil. The oil cons umption may be as much as
0.5 l/1 000 km depending on your style of driving and the conditions under which
you operate your vehicle. The oil consumpt ion may be slightly higher than this
during the first 5 000 kilometres.
One should therefore check the oil level at regular intervals, preferably every time
after the fuel tank is filled or after driving for long stretches.
We recommend maintaining the oil level within the range if the engine has been
operating at high loads, for example during a lengthy motorway trip during the
summer months, towing a trailer or negotiating a high mountain pass, but not
above this .
The warning light in the instrument cluster* will indicate ⇒page 35, “Engine oil
level* ” whether the oil level is too low. In this case, check the oil level as soon as
possible. Top up with an a ppropriate quantity of oil.
Caution
•The oil level must on no account ex tend beyond the range . Danger of
damaging the catalytic converter.
•Do not continue your journey if for some reason it is not possible under the
conditions prevailing to top up with oil. Switch of the engine and contact and
obtain professional assistance from a specialist garage.
Replenishing engine oil
– Inspecting the engine oil level ⇒page 211.
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres ⇒page 210.
– Inspect the oil level ⇒page 211, “Check engine oil level”.
– Carefully screw on the cap of the filler opening and push the dipstick in fully.
WARNING
•Avoid dripping oil onto hot parts of the engine when topping up will oil -
a risk of fire!
•Read and observe the warning notes ⇒page 209, “Working in the engine
compartment” before working in the engine compartment.
For the sake of the environment
The oil level must on no account be above the range ⇒page 211. Oil will other-
wise be drawn in through the crankcase ventilation and may pass through the
exhaust system to atmosphere. The oil ma y combust in the catalytic converter and
damage it.
Changing engine oil
The engine oil must be changed at the intervals stated in the Service schedule or
according to the service interval indicator ⇒page 12, “Service Interval Display”.
WARNING
•Only carry out the engine oil change, if you have the required profes-
sional knowledge!

•Read and observe the warning notes ⇒page 209, “Working in the engine
compartment” before working in the engine compartment.
•Let the engine cool down - risk of burning from hot oil.
•Wear an eye protection - risk of caustic burns due to oil splashes.
•Oil is toxic! Store old oil in a safe place out of the reach of children and
unauthorized persons until you dispose of it properly.
Caution
You must not pour any additives into th e engine oil - risk of engine damage!
Damage, which results from such produc t, are excluded from the warranty.
For the sake of the environment
•You must on no account pour oil into the ground or into the sewage system.
•In view of the problems involved in prop erly disposing of old oil, the material,
equipment and the knowledge required for such work, we recommend that you
have the oil and oil filter change carried out by your Škoda Service Partner.
Note
After your skin has come in contact with the oil, you must thoroughly wash your
skin.
Cooling system
Coolant
The job of the coolant is to cool the engine.
The cooling system does not require an y maintenance under normal operating
conditions. The coolant consists of water with a concentration of coolant additive
of 40 %. This mixture not only provides antifreeze protection down to -25°C but also protects the cooling and heating system
from corrosion. It also prevents the
formation of scale and significantly increases the boiling point of the coolant.
You must therefore not reduce the concentration of antifreeze agent in the coolant
by adding water, also not during the su mmer months or in countries with a warm
climate. The concentration of coolant additive in the coolant must be at least
40%.
You can increase the amount of antifreeze in the coolant if a higher concentration
of antifreeze is necessary for climatic reasons but only up to 60% (antifreeze
protection down to approx. -40°C). The an tifreeze protection tails off above that
concentration.
Vehicles exported to countries with a co ld climate (e.g. Sweden, Norway, Finland)
are already factory-filled with a coolant which offers antifreeze protection down to
about -35°C. In these countries the concentr ation of coolant additive should be at
least 50 %.
Coolant
The cooling system is filled at the works with coolant (purple in colour), which
complies with the specification TL-VW 774 F.
We recommend that you use the same c oolant additive - G12 PLUS (purple in
colour).
Please contact your Škoda Se rvice Partner if you have any questions regarding the
coolant or if you wish to fill up with a different coolant.
Your Škoda Service Partner can also suppl y you with the correct coolant additives.
Caution
•Other coolant additives may cause operational problems which, in partic-
ular, involves significantly reducing the anticorrosion effect.
•Any faults or problems resulting from corrosion may cause a loss of
coolant and, as a consequence of th is, result in major engine damage.

Inspecting the coolant level
The coolant expansion bottle is loca ted in the engine compartment on
the right.
– Switch the engine off.
– Open the bonnet ⇒page 209, “Working in the engine compartment”.
– Check the level of coolant in the coolant expansion bottle ⇒fig. 189 .
The coolant level when the engine is cold must lie between the
(MIN) and (MAX) markings. The level may also rise slightly above
the (MAX) marking when the engine is warm.
If the coolant level in the reservoir is too low, this is indicated by the warning light
in the instrument cluster  ⇒ page 31. We nevertheless recommend inspecting
the coolant level directly at th e reservoir from time to time.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the system. You
should not merely top up the coolant in the reservoir. It is also important to have
the cooling system inspected without delay by a specialist garage.
Losses can only occur through the pressure relief in the cap of the coolant expan-
sion bottle which is completely free of leak s if the coolant boils as a result of over-
heating and is forced out of the cooling system.
WARNING
Read and observe the warning notes ⇒page 209, “Working in the engine
compartment” before working in the engine compartment.
Caution
One should contact a specialist garage as soon as possible if the source of over-
heating itself cannot be determined and removed, since there may be grave
damage to the engine.
Replenishing the coolant
– Switch the engine off.
– Allow the engine to cool down.
– Place a cloth over the cap of the coolant expansion reservoir ⇒fig. 189 and unscrew the cap carefully by turning it to the left
⇒ .
– Top up the coolant.
– Screw the cap tight until it is heard to lock.
The coolant which you use for replenishing the system, must comply with one
specific specification ⇒page 213, “Coolant”. Do not use an alternative additive if
the coolant additive G12 PLUS is not available in exceptional cases. Just top up the
system with water and as soon as possible arrange adjustment to correct the mixing
ratio of water and coolant additive again by a specialist garage.
Only use fresh coolant for topping up the system.
Do not fill up over the “MAX” marking! Excess coolant which is heated up is forced
out of the cooling system through the pressure relief valve in the cap of the coolant
compensation bottle.
Wait until the engine has cooled down for a system which has suffered a major loss
of coolant before pouring in coolant. This is necessary to avoid engine damage.

WARNING
•The cooling system is pressurized! Do not open the cap of the coolant
expansion bottle if the engine is still hot - risk of scalding!
•The coolant additive and thus all of the coolant is harmful to your health.
Avoid contact with the coolant. Coolant vapours are also harmful to the
health. It is important, therefore, to always safely store any coolant additive
in its original container out of the reach of children - risk of poisoning!
•If any splashes of coolant get into yo ur eyes, rinse out your eyes immedi-
ately with clear water and contact a doctor as soon as possible.
•You should also consult a doctor without delay if you have inadvertently
swallowed coolant.
Caution
Do not continue your journey if for some reason it is not possible under the
conditions prevailing to top up with coolant. Switch of the engine and contact
and obtain professional assistance from a specialist garage.
For the sake of the environment
Do not re-use coolant if it is necessary to drain the coolant in the system. It should
be collected and disposed of in comp liance with environmental protection
regulations.
Radiator fan
The radiator fan may switch on suddenly.
The radiator fan is driven by an electric motor and controlled according to the
coolant temperature.
The radiator fan may continue running fo r up to 10 minutes after the engine has
been switched off - even if the ignition is also off. It may also switch on suddenly
after a certain time, if
•the coolant temperature ha s risen because of an accumulation of heat or
•the warm engine compartmen t is heated up additionally by strong sunlight.
WARNING
You must therefore be aware when working in the engine compartment that
the fan may switch on suddenly - risk of injury!
Brake fluid
Inspecting the brake fluid level
The brake fluid reservoir is located on the left of the engine compartment.
The brake fluid reservoir on right-hand steering models is positioned on
the other side of the engine compartment.
– Switch the engine off.
– Open the bonnet ⇒page 209, “Working in the engine compartment”.
– Inspect the brake fluid level in the reservoir ⇒fig. 190 . The level must
be between the “MIN” and “MAX” markings.
A slight drop in the fluid level results when driving due to normal wear-and-tear
and automatic adjustment of the br ake pads, and is perfectly normal.

There may be an indication of a leak in th e brake system, however, if the fluid level
drops significantly within a short time or if it drops below the “MIN” marking. A situ-
ation where the brake fluid level is too low is indicated by the warning light

lighting up in the instrument cluster ⇒page 34. In this case stop immediately and
do not drive any further! Obta in professional assistance.
WARNING
•Read and observe the warning notes ⇒page 209 before working in the
engine compartment.
•If the fluid level has dropped below the MIN marking, do not drive any
further - risk of accident! Contact a Škoda dealer to obtain professional
assistance.
Replacing brake fluid
Brake fluid absorbs moisture. This causes the fluid to absorb moisture from the
surrounding air over a period of time. Excessive water in the brake fluid may be the
cause of corrosion in the brake system. Th e water content also lowers the boiling
point of the brake fluid. This is why brake fluid must be replaced every two
years.
One may only use new genuine brake fluid from Škoda Auto a.s. The specification
for the brake fluid is “FMVSS 116 DOT 4”.
We recommend that you have the brake fluid replaced by a Škoda Service Partner
as part of an Inspection Service.
WARNING
•Using old brake fluid can result in seve re stress on the brakes because of
the formation of vapour bubbles in the brake system. This greatly impairs
the braking efficiency and thus also the safety of your vehicle.
•Brake fluid is toxic! It must therefore be kept safely in closed original
containers and well aw ay from children and unauthorized persons.
Caution
Brake fluid damages the paintwork of the vehicle.
For the sake of the environment
In view of the problems involved with prop er disposal of brake fluid, the special
tools and the professional knowledge required, you should have the brake fluid
replaced by a Škoda Service Partner.

Removal and installation of the battery is not recommended since it can, under
certain circumstances, lead to major damage. Contact a specialist garage.
There is a risk of injuries, scalding, acci dents and burns when carrying out any work
on the battery and on the electrical system. For this reason, it is essential to comply
with the warning instructions ⇒ stated below and with the general applicable
rules of safety.
WARNING
•The battery acid is strongly corrosive and must, therefore, be handled
with the greatest of care. Always we ar protective gloves, eye and skin
protection when handling batteries. Corrosive fumes in the air irritate the
air passages and lead to conjunctivitis and inflammation of the air passages
in the lungs. Battery acid corrodes de ntal enamel and creates deep wounds
after contact with the skin which take a long time to heal. Repeated contact
with diluted acids causes skin diseases (inflammations, ulcers, slin cracks).
Acids coming into contact with water are diluted accompanied by significant
development of heat.
•Do not tilt the battery otherwise battery electrolyte may flow out of the
battery vent openings. Protect the eyes with safety glasses or a shield! There
is the danger of suffering blindness! If any battery electrolyte gets into your
eye, rinse out your eye immediately with clear water for several minutes.
Contact a doctor without delay.
•Splashes of acid on your skin or clothes should be neutralised as soon as
possible using soap suds and then rinsed with plenty of water. Contact a
doctor immediately if you swallow battery electrolyte.
•Keep batteries out of the reach of children.
•Hydrogen is released when you char ge a battery and a highly explosive
gas mixture is produced. An explosion can be caused through sparkling over
during unclamping or loosening of the cable plug while the ignition is on.
•Bridging of the poles will create a short circuit (e.g. through metal
objects, cables). Possible consequences of a short circuit: Melting of lead
struts, explosion and burning of the battery, jets of acid spurting out.
•It is prohibited to work with a naked flame and light, to smoke or to carry
out any activities which produce sparks. Avoid creating sparks when
working with cables and electrical device s. Strong sparking represents a risk
of injury.
•Before carrying out any work on the electrical system, switch off the
engine, the ignition as well as all electrical components and disconnect the
negative cable (-) on the battery. If you wish to replace a bulb it is sufficient
to switch off the appropriate light.
